To all whom zt may concern:

Be it known that I, JOHN R. GAMMETEB, a citizen of the United States,residin at Akron, in the county of Summit and tate of Ohio,;havinginvented a certain new and useful Smiling-Box for Balloon-Cords, o.

vvliicli the following is a specication.

This invention has for its principal object to provide a substantiallyfluid-tight guide and stuliingebox for a :flexible cord used on eballooon, such as the pull-cordior the rip-panel, ai the point Wheresaid cord passes through the wall envelop. The invention may, however,be employed in any analogous or appiopiieie situation. A

@i the accompanying drawings,

Figure l is a side eleyetion ori one end ci e balloon envelop, showingtee general eirangement of the rip-panel and cond.

Fig. 2 is a longitudinal sectionel view showing a guide oi' sending-boxembodying my invention, together with tbe cord nessing tbei'etbrougb.

Fig. 8 is a cross-seelion on ille line 3-3 of 2. i

ln tbe drawings, l0 is the balloon envelop oi gas bag having a row oiemergency oui lets 1l on top, coniiolled by tbe usuel rip-- panel l2which is arranged on tlie inside on a transveise arc, le the remote endoi said panel. ,The nipcord leads from the outside tbiougii e.

'l` e sboii, iubulai body 18 is oimed Willi e.bese-danse i9 located on tbe innen side of the wall .oi elle balloonenvelop, and saidange is ieced with fabric disks 20, 2l`cementedtherese, there beine a soit-rubber packing disk 22 internosedqoetweenthe outer labile disk 2l andllie inner side of the envelop l0, contieneed to bolli fabric surfacesy and formed witli a collar 23 which embraceselle cylindrical gai-t of the metal body 18, said collar and i ody beingformed withintertting grooves and ribs asindicated at 24.

of the gas bag oi i lbeing elle nemn end end with eachl other, or t Theinner end of the body 18 is formed with en annular ledge or shoulder 25,and into its outer lend is screwed the tubular gland or sleeve 26, theouterend of the latter having a daring eye or guide aperture 27 for thecord. lhe twopackin sleeves 28, composed of vulcanized soft iu ber, are

.formed with cylindrical base enlargements or flanges 29 which are heldunder coinpiession, in abuitine; relation, in tbe central cavity of thebody i8, between the shoulder andv be inner end of the gland 26. Eachel? these sleeves is inlernally'iinolded Wil-b. a series oi integral,exible spaced, annular, free-edged packing each,.in tbe preferredform/lierre sbovvn, baving ageneral conical Jform and mening an acuteangle with ille exis of the corel so 'that the les-lier will slidethrough tbe lips in either direction Without snubbing oi1 catching-ilieieon kecb. lip pseleiably beers against tbe cond with only e lightpressure ci iis own, and there sie a suilcient number of elle lipsiso'provide e ti bt pack? ing Witboui an encessive amount oi friction.The lips on tbe inner sleeve 28 are directed exially inweid end those onthe :outer sleeve 28 are direeied exially onward, so elles either tliegas pi'essuie 1Within the balloon or the ennospbeiic psessuie on tbeoutside (eccoi'ding to 'which piedoniinetes) will send to compress tbeseid lips against elle ccnl le end peevene any substeniiel amounto'iileakage sieben wey.
